TECHNIQUE: Extraction liquide-liquide - Zysman-Colman
Extraction liquide-liquide 2 Extraction liquide-liquide L’extraction liquide-liquide est une méthode de purification basée sur la différence de solubilité d’un soluté dans deux phases non miscibles En chimie organique, on utilise habituellement une phase aqueuse et une phase organique Matériel utilisé: • Ampoule à décanter
09 Liquid-Liquid Extraction - t U
Liquid-Liquid Extraction (LLE) Extraction is a process where one or more solute(s) are removed from one liquid phase (technically called a diluent) by transferring that/those the solute(s) to another liquid phase (or a solvent) Since this is the operation between the two liquid phases, no vaporisation is needed; thus,

lation, in some cases by an additional extraction, and usually requires much expense Whether a separation sequence using an extraction step is recommended can only be decided by evaluating the cost effective-ness of the complete process In spite of its significant expense, the liquid-liquid-extraction can be more economic than a direct recti-

Design of Liquid-Liquid Extraction Columns
The equipment from extraction can be a series of countercurrent stages, each consisting of a mixer and a decanter or settler, arranged in a countercurrent cascade, or in a tray or packed tower, as Figure 1 shows Figure 1 Extraction Cascade of Mixers and Settlers, and Extraction Tray Tower
87 Solid liquid extraction
8 7 Solid – liquid extraction 8 7 1 Theoretical background Solid – liquid extraction (or leaching) is the separation of a solid solute from a mixture of solids by dissolving it in a liquid phase Basically, there are three com-ponents in leaching: solid solute, insoluble solids and solvent In most cases, the
